Background: The purpose of this study was to investigate the effects of WBC (whole-body cryotherapy)on the MVIC (maximal voluntary isometric contraction)and active ROM (range of motion) recovery of after EIMD (exercise-induced muscle injury). Design: Randomized Controlled Trial. Methods: Thirty subjects who are student in their 20s at a university participated in this study, these subjects were assigned into three groups, a control group (n=10), experiment group I(n=10), and experiment group II (n=10). The subjects in the experimental group II were intervened by WBC (-130℃, 3 minutes) before induced EIMD, the experimental group were intervened by WBC (-130℃, 3 minutes) after induced EIMD, and the control group weren't by any intervened after induced EIMD. Results: First, In the comparison of the MVIC, there were significant variations with the lapse the time in three groups (p<.001) and there was a significant interaction of time and group (p<.001). In the among group comparison, the MVIC of experimental group II was significantly larger than those of other groups (p<.001). Second, In the comparison of the active extension angle, there were significant variations with the lapse the time in three groups (p<.001) and there was a significant interaction of time and group (p<.001). In the among group comparison, the active extension angle of experimental group II was significantly smaller than those of other groups (p<.001). Third, In the comparison of the active flexion angle, there were significant variations with the lapse the time in three groups (p<.01) and there was a significant interaction of time and group (p<.001). In the among group comparison, the active flexion angle of experimental group II was significantly larger than those of other groups (p<.05). Conclusion: The above results revealed that the WBC intervention after an exercise had a positive effect of muscle function after EIMD. Therefore we can consider the WBC as a considerable intervention method to prevent or reduce an exercise injury.

Broncholiths are defined as calcified materials that occur in a tracheobronchial tree or in a cavity communicating with that. Broncholith has variable clinical features. The therapeutic options to remove broncholiths are so variable that clinicians need to select the most safe and effective methods by mass size, mobility, and location. As yet, there is no consistent guideline removing a broncholith. We report 2 successful cases of removing a fixed broncholith by flexible bronchoscopy guided cryoadhesion. With repeated technique of thawing and freezing with cryoprobe, we could extract the fixed broncholith safely. This method is promising as a way to remove broncholith in the future.

Purpose: To study clinical factors related to adequacy of transformation zone (TZ) components in cervical smears. Materials and Methods: Medical and Papanicolaou (Pap) smear reports from Thammasat University Hospital, Thailand during January to December 2015 were collected. Demographic data was reviewed by attending physicians and impact of clinical factors onTZ adequacy was primary outcome. A total of 3,251 smears were reviewed. Finally, 2,098 smears met The inclusion criteria and enrolled into this study. Results: Average age and bodyweight of participants in this study were 43.0 years and 60.0 kg, respectively. Ninety seven percent of smears were classified as satisfactory for evaluation according to the Bethesda system 2001. Adequacy (group A) and inadequacy (group B) of TZ were equal in percentage (50.9/46.0). Prevalence of abnormal cervical cytology was 4.4%. Percentages of abnormal Pap smears in group A and B were 7.3 and 1.4, respectively (p<0.001). Factors associated with increased adequacy of TZ were old-age (${\geq}50yr$), nulliparity, within 3-months postpartum, history of TZ inadequacy and abnormal smears. Sexually transmitted disease (STD), hormonal usage, previous cryotherapy and smears collected by staff were associated with inadequacy of TZ. Conclusions: Collection of cervical specimens should be carefully performed. STD history, hormonal usage and previous cryotherapy are risk factors for TZ inadequate specimens.

Objectives : This study aimed to investigate temperature characteristics by heat transfer type of therapeutic modalities. Methods : We selected heating and cooling modalities that are frequently used in clinical by heat transfer type: conduction, convection, radiation, and conversion. We used ham as tissue model, and applied the modalities for 30 minutes. We measured real-time changed temperature($^{\circ}C$) of the surface, 2, 4, 6, 8, 10, 12, and 14 mm depth. Results : 1. In conduction-using hot pack, ice pack, and CryoStamp heating-cooling combination therapy unit($40^{\circ}C/{\sim}15^{\circ}C$), the surface temperature sharply rose close to equilibrium in first 5 minutes. 2. In convection-using smokeless moxa, temperature slowly rose to the maximum at 25-minute elapsed time. But in another convection-using CRAiS cryotherapy device, result was similar to that of conduction. 3. In radiation-using infrared lamp, result was similar to that of conduction, but not reached equilibrium during applying time. 4. In conversion-using ultrasound device, temperature was the highest at 6 mm depth, and not reached equilibrium during applying time. Conclusions : We could comprehend temperature characteristics and proper use of modalities by heat transfer type. It would be necessary to consider in vivo physical conditions in further studies.

Background: The purpose of this study was to investigate the effects of WBC on the pressure pain threshold, CK and LDH after exercise-induced muscle injury. Design: A Randomized Controlled Trial. Methods: In this study, these subjects were assigned into three groups, a control group (n=10), experiment group I (n=10) and experiment group II (n=10). The subjects in experimental group I were intervened by WBC (-130℃, 3 minutes) before induced EIMD, experimental group II were intervened by WBC (-130℃, 3 minutes) after induced EIMD and control group weren't by any intervened after induced EIMD. Results: First, In the comparison of the PPT, there were significant variations with the lapse the time in three groups (p<.001) and there was a significant interaction of time and group (p<.001). In the among group comparison, the PPT of experimental group II was significantly larger than those of other groups (p<.01). Second, In the comparison of the CK, there were significant variations with the lapse the time in three groups (p<.001) and there was a significant interaction of time and group (p<.001). In the among group comparison, the CK of experimental group II was significantly smaller than those of other groups (p<.001). Third, In the comparison of the LDH, there were significant variations with the lapse the time in three groups (p<.01) and there was a significant interaction of time and group (p<.001). In the among group comparison, the LDH of experimental group II was significantly smaller than those of other groups (p<.001). Conclusion: The above results revealed that the WBC intervention after an exercise had a positive effect of muscle function after EIMD.

Hemangioma and vascular malformation is a common vascular benign lesion in the head and neck region. The lesion is a congenital malformation observed in neonates. The treatment this lesion includes surgical excision, cryotherapy, selective embolization and treatment with sclerotic agents. We present three cases of benign oral vascular lesions treated with an intralesional injection of sodium tetradecyl sulfate. The lesions virtually disappeared after three sessions of sclerotherapy, leaving an inconspicuous scar. No side effects were observed. Sclerotherapy with sodium tetradecyl sulfate is effective in treating benign oral vascular lesions, and the use of the sodium tetradecyl sulfate provides alternative or support for surgical methods.

Retinopathy of prematurity (ROP) is a major cause of blindness that affects premature infants. With advances in neonatology, ROP is likely to emerge as the most serious problem of vision loss in children even in developed countries; such a situation could be called the third epidemic of ROP. However, controversy and uncertainty still surround favorable outcomes of ROP. For successfully controlling ROP, timely and accurate screening is crucial because early treatment leads to favorable outcomes. Standard guidelines, including ROP classification, have provided satisfactory instructions for the screening and treatment of ROP. To improve the structural and functional outcomes of ROP, optimizing the timing of surgical interventions including cryotherapy, laser-photocoagulation, encircling, and vitrectomy is essential; these interventions can prevent the sequelae of ROP. It is essential for the neonatologist and the ophthalmologist to cooperate extensively for the successful treatment of ROP.

We reviewed literatures of western and oriental medicine about postoperative management of spine. Traditionally, with orthoses and bed rest, many physicians restricted activity of daily life and back exercises of patients who had taken spine surgery. More aggressive early mobilization, however, such as strengthening exercise and stretching after 4 weeks of surgery gets grounds nowadays. Physical therapies including manipulation, TENS, MENS, ultrasound and cryotherapy are being used as helpful treatment modalities of postoperative pain and swelling. Failed back surgery syndrome occurs due to wrong patient, diagnosis and surgery and is managed with conservative treatment or reoperation. In oriental medicine, treatments of musculoskeletal injuries including surgical wound are based on the balance of chi(氣) and blood(血).
